Denon AVR-X2500H Service Manual

Check the power supply voltage. (HDMI Rx)
Check item(11). Check the power supply voltage. :
Does the power supply voltage of the HDMI Rx1 [U1000] indicate the correct voltage (1.1V, 3.3V)?
The test points are as follows.
HDMI Rx1
U1000
112 pin
38 pin
1.1V
3.3V
Check item(12). Check the power supply voltage. :
Check the power components [U1063/U1066] and the pattern on
the substrate.
If there is no problem, remove the HDMI Rx [U1000] from the sub-
strate and measure the voltage at the test point of check item (11).
Is the voltage correct (1.1V or 3.3V)?
Replace with a new device.
The power supply circuit is
faulty.
Replace the PCB.
Recheck from check item (1).
If it does not work, replace the PCB.

Checking the reset waveform. (HDMI Rx)
Check item(13). Checking the reset waveform :
Check the waveform.
Is the "RESET" waveform of the TP near the HDMI Rx [U1000]
correct (like the one shown in the diagram) when the power is
turned on?
HDMI Rx1
U1000
RESET
Check the reset circuit between
CPU [U1018] and HDMI Rx
[U1000].
If there is no problem, the HDMI
Rx [U1000] is faulty.
Replace with a new device.
Recheck from check item (1).
If it does not work, replace the
PCB.
